I assume it's "thermal" (heating coil -> convection) as opposed to microwave. Why this the terminology is this way when the end result is a rise in thermal units of measure (temperature) I don't know.
My parents did, long ago. It was like a teapot except for coffee, you poured the hot water in the top. No electrical/heating components, therefore non-thermal.
